Hmmmm . . . that doesn't look like crochet to me. It looks knitted--particularly the garter stitch followed by a row of knit/purl (maybe?). I'm not sure what the inside of the flower is. No doubt it's some kind of increase.

The central motif on this crocheted flower looks similar to the one you posted (scroll down the photo A). You might try searching the Lionbrand site too. They've done lots of knit and crochet flowers over the past few years.
